commit 656299f706e52e0409733d704c2761f1b12d6954
(vlan: convert to net_device_ops) added a net_device_ops
with a NULL ndo_start_xmit field.This gives a crash in dev_hard_start_xmit()
Fix it using two net_device_ops structures, one for hwaccel vlan,
one for non hwaccel vlan.Signed-off-by: Eric Dumazet

The changes to deliver hardware accelerated VLAN packets to packet
sockets (commit bc1d0411) caused a warning for non-NAPI drivers.
The __vlan_hwaccel_rx() function is called directly from the drivers
RX function, for non-NAPI drivers that means its still in RX IRQ
context:[ 27.779463] ------------[ cut here ]------------

in softirq context, performs the real reception and delivery to

This enables more ethtool information. The speed and settings of the
underlying device are propagated up. This makes services like SNMP that
use ethtool to get speed setting, work when managing a vlan, without adding
silly heurtistics into SNMP daemon.For the driver info, just use existing driver strings.

The vlan devices are not reading the gso max size of the parent device. As

alloc_netdev_mq() now allocates an array of netdev_queue
structures for TX, based upon the queue_count argument.Furthermore, all accesses to the TX queues are now vectored
through the netdev_get_tx_queue() and netdev_for_each_tx_queue()
interfaces. This makes it easy to grep the tree for all
things that want to get to a TX queue of a net device.Problem spots which are not really multiqueue aware yet, and
only work with one queue, can easily be spotted by grepping
for all netdev_get_tx_queue() calls that pass in a zero index.Signed-off-by: David S. Miller

When VLAN header stripping is used, packets currently bypass packet
sockets (and other network taps) completely. For locally existing
VLANs, they appear directly on the VLAN device, for unknown VLANs
they are silently dropped.Add a new function netif_nit_deliver() to deliver incoming packets
to all network interface taps and use it in __vlan_hwaccel_rx() to
make VLAN packets visible on the underlying device.Signed-off-by: Patrick McHardy

- vlan_dev_reorder_header() is only called on the receive path after
calling skb_share_check(). This means we can use skb_cow() since
all we need is a writable header.- vlan_dev_hard_header() includes a work-around for some apparently
broken out of tree MPLS code. The hard_header functions can expect
to always have a headroom of at least there own hard_header_len
available, so the reallocation check is unnecessary.- __vlan_put_tag() can use skb_cow_head() to avoid the skb_unshare()
copy when the header is writable.Signed-off-by: Patrick McHardy

The VLAN code contains multiple spots that use tag, id and tci as
identifiers for arguments and variables incorrectly and they actually
contain or are expected to contain something different. Additionally
types are used inconsistently (unsigned short vs u16) and identifiers
are sometimes capitalized.- consistently use u16 for storing TCI, ID or QoS values
- consistently use vlan_id and vlan_tci for storing the respective values
- remove capitalization

The function is huge and included at least once in every VLAN acceleration
capable driver. Uninline it; to avoid having drivers depend on the VLAN
module, the function is always built in statically when VLAN is enabled.With all VLAN acceleration capable drivers that build on x86_64 enabled,
this results in:text data bss dec hex filename

Lennert Buytenhek points out that the VLAN code incorrectly adjusts
skb->network_header to point in the middle of the VLAN header and
additionally tries to adjust skb->mac_header without checking for
validity.The network_header should not be touched at all since we're only
adding headers in front of it, mac_header adjustments are not
necessary at all.Based on patch by Lennert Buytenhek .

Add GVRP support for dynamically registering VLANs with switches.
By default GVRP is disabled because we only support the applicant-only
participant model, which means it should not be enabled on vlans that
are members of a bridge. Since there is currently no way to cleanly
determine that, the user is responsible for enabling it.The code is pretty small and low impact, its wrapped in a config
option though because it depends on the GARP implementation and
the STP core.Signed-off-by: Patrick McHardy

Move rcu-protected lists from list.h into a new header file rculist.h.
This is done because list are a very used primitive structure all over the
kernel and it's currently impossible to include other header files in this
list.h without creating some circular dependencies.For example, list.h implements rcu-protected list and uses rcu_dereference()
without including rcupdate.h. It actually compiles because users of
rcu_dereference() are macros. Others RCU functions could be used too but
aren't probably because of this.Therefore this patch creates rculist.h which includes rcupdates without to
many changes/troubles.Signed-off-by: Franck Bui-Huu
